War is a simple card game, typically played by two players using a standard playing card deck — and often played by children. There are many variations, as well as related games such as the German 32-card Tod und Leben.
A "war" in the game of War: having dealt matching 7s, both players play a stack of three face-down cards on top of their card, followed by a face-up card. In this case, the king wins.

A card game is any game that uses playing cards as the primary device with which the game is played, whether the cards are of a traditional design or specifically created for the game (proprietary). Countless card games exist, including families of related games. A small number of card games played with traditional decks have formally standardized rules with international tournaments being held, but most are folk games whose rules may vary by region, culture, location or from circle to circle.
